PSYCHROMETRIC TABLES
MEASUREMENT OF ATMOSPHERIC MOISTURE. — The quantity of
moisture mixed with, the air under different conditions of tempera-
ture and degree of saturation may be measured in several dis-
tinctly different ways. Many of these, however, are not practicable
methods for daily observations, or are not sufficiently accurate.
Probably the most convenient of all methods and the one most
generally employed is to observe the temperature of evaporation —
that is, the difference between the temperatures indicated by wet
and dry-bulb thermometers. The most reliable instrument for
this purpose is the sling, or whirled psychrometer. In special
cases rotary fans, or other means, may be employed to move the
air rapidly over the thermometer bulbs. In any case satisfactory
results can-not be obtained from observations in relatively stag-
nant air. A strong ventilation is absolutely necessary to accuracy.
SLING PSYCHROMETER. — This instrument consists of a pair of
thermometers, provided with a handle as shown in fig. 1, which
permits the thermometers to be whirled rapidly, the bulbs being
thereby strongly affected by the temperature of and moisture in
the air. The bulb of the lower of the two thermometers is covered
with thin muslin, which is wet at the time an observation is made.
THE WET-BULB. — It is important that the muslin covering for
the wet-bulb be kept in good condition. The evaporation of the
water from the muslin always leaves in its meshes a small quantity
of solid material, which sooner or later somewhat stiffens the mus-
lin so that it does not readily take up water. This will be the case
if the muslin does not readily become wet after being dipped
in water. On this account it is desirable to use as pure water as
possible, and also to renew the muslin from time to time. New
muslin should always be washed to remove sizing, etc., before
being used. A small rectangular piece wide enough to go about
one and one-third times around the bulb, and long enough to cover
the bulb and that part of the stem below the metal back, is cut
out, thoroughly wetted in clean water, and neatly fitted around the
thermometer. It is tied first around the bulb at the top, using a
moderately strong thread. A loop of thread to form a knot is
next placed around the bottom of the "bulb, just where it begins to
round off. As this knot is drawn tighter and tighter the thread
sjlips off the rounded end of the bulb and neatly stretches the mus-
lin covering with it, at the same time securing the latter at the
bottom.

To MAK^ AN OBSERVATION. — The so-called wet-bulb is thoroughly
saturated with water by dipping it into a small
cup or wide-mouthed bottle. The thermometers
are then whirled rapidly for fifteen or twenty
seconds; stopped and quickly read, the wet-bulb
first. This reading is kept in mind, the psychrome-
ter immediately whirled again and a second reading
taken. This is repeated three or four times, or more,
if necessary, until at least two successive readings
of the wet-bulb are found to agree very closely,
thereby showing that it has reached its lowest tem-
perature. A minute or more is generally required
to secure the correct temperature.
When the air temperature is near the freezing
point it very often happens that the temperature of
the wet-bulb will fall several degrees below freez-
ing point, but the water will still remain in the
liquid state. No error results from this, provided
the minimum temperature is reached. If, however,
as frequently happens, the water suddenly freezes,
a large amount of heat is liberated, and the tem-
perature of the wet-bulb immediately becomes 32°.
In such cases it is necessary to continue the whirl-
ing until the ice-covered bulb has reached a mini-
mum temperature.
WHIRLING AND STOPPING THE PSYCHROMETER. —
It is impossible to effectually describe these move-
ments. The arm is held with the forearm about
horizontal, and the hand well in front. A peculiar
swing starts the thermometers whirling, and after-
ward the motion is kept up by only a slight but
very regular action of the wrist, in harmony with
the whirling thermometers. The rate should be a
natural one, so as to be easily and regularly main-
tained. If too fast, or irregular, the thermometers
may be jerked about in a violent and dangerous
manner.
The stopping of the psychrometer, even at the
very highest rates, can be perfectly accomplished
in a single revolution, when one has learned the
knack. This is only acquired by practice, and con-
sists of a quick swing of the forearm by which the
hand also describes a circular path, and, as it were,
follows after the thermometers in a peculiar man-
ner that wholly overcomes their circular motion
FlG. 1.— StINO PSY-
CH ROM ETEK.
without the slightest shock or jerk. The thermometers may, with-
out very great danger, be allowed simply to stop themselves ; the
final motion in such a case will generally be quite jerky, but, unless
the instrument is allowed to fall on the arm, or strikes some object,
no injury should result.
EXPOSURE. — While the psychrometer will give quite accurate
indications, even in the bright sunshine, yet observations so made
are not without some error, and, where greater accuracy is desired,
the psychrometer should be whirled in the shade of a building or
tree, or, as may sometimes be necessary, under an umbrella. In
all cases there should be perfectly free circulation of the air, and
the observer should face the wind, whirling the psychrometer
in front of his body. It is a good plan, while whirling, to step
back and forth a few steps to further prevent the presence of the
observer's body from giving rise to erroneous observations.
DEW-POINT APPARATUS. — The apparatus shown in .fig. 2 is a
modified form of Regnault's apparatus, and serves to determine
directly the temperature of the dew-point. It consists essentially
of a thin polished silver tube, a, cemented upon the lower end of
a longer glass tube, as shown. The stopper closing the upper end
of this tube is fitted with two lateral tubes of hard rubber, b and c,
and carries a delicate thermometer, the bulb of which is placed
near the center of the silver tube. The tube b extends to the bot-
tom of the silver tube; c projects but a short distance through the
cork. A rubber aspirating apparatus, as shown, is connected with
the tube fr, and a long tube joined to c serves to carry off the fumes
generated in the apparatus. The glass tube is held in a clamp
faced with cork, which largely intercepts the transfer of heat.
Observations are made by filling the silver cup with sulphuric
ether, or similar volatile liquid, which is caused to evaporate and
cool the silver cup in the desired manner by manipulating the
aspiration bulb. At the proper point of cooling, a deposit of dew
is seen to form on the polished silver surface. The object is to
ascertain accurately the temperature at which the dew will just
deposit. For this purpose it is necessary that the temperature be
lowered very slowly at the critical point, also that there be plenty
of liquid in the cup and that it be agitated sufficiently to have a
uniform temperature throughout. Finally, the surface of the
silver must be perfectly clean and in a favorable light, so that the
faintest deposition of dew is at once visible. The temperature
shown by the thermometer at this moment may be regarded as the
temperature of the dew-point.
In order that the presence of the observer shall not affect the
moisture contents of the air in the vicinity of the cup during an
observation, it is necessary that in breathing he exhale through a
suitable tube which will conduct the moist air from his lungs to a
sufficient distance. It is further advisable that a very gentle
motion be given to the air near the cup by use of an ordinary fan.
For the greatest accuracy, the cup should be allowed to warm up
and the deposition of dew formed several times in succession, a
reading of the temperature being made at each deposition.

FAULTY CONCEPTIONS.— A false notion that the air has a cer-
tain capacity for moisture is widely prevalent, and is perpetuated
by all such expressions as ' ' The air is partly saturated with moist-
ure," ;' Weight of aqueous vapor in a cubic foot of saturated
air" etc.
It should always be clearly observed that the presence of the
moisture in any given space is independent of the presence or
absence of air in the same space except that the air retards the
diffusion of the vapor particles. It is more correct to say, in the
above cases, that the space is partly saturated with moisture, or
that the moisture is in a partly saturated condition or is super-
heated. By all means use the phrase ' ' Weight of a cubic foot of
saturated aqueous vapor," not "Weight of aqueous vapor in a
cubic foot of saturated air."
THE PSYCHROMETRIC FORMULA. — The values of relative humid-
ity, and the temperature of dew-points given in the accompanying
tables, have been computed by means of the following formula,
deduced by Professor Ferrel,*
(
in which t and t' are the temperatures of the dry and wet bulb
thermometers, P is the barometric pressure of the air in inches,
all corrections having been applied, and e' is the maximum or sat-
uration pressure of aqueous vapor at the temperature t' of the wet
bulb.
The solution of the equation gives e, the pressure of the aqueous
vapor corresponding to the observed temperatures t and t'.
The constants of the formula were deduced from a large series
of experiments made by the writer in Colorado Springs, Colo.,
and at different elevations on Pike's Peak. These experiments were
supplemented by similar observations made in Washington by
Prof. H. A. Hazen and the writer, and include a considerable
number of experiments at temperatures below the freezing point
by Professor Hazen.
In the experiments referred to, the sling, or whirled psychrome-
ter, was employed to ascertain the difference, t — t\ between the
wet and dry bulb temperatures, and simultaneous determinations
were also made of the temperature of the dew-point by means of
modified forms of the Regnault and the Alluard dew-point appara-
tus. The modified Regnault apparatus is described in a preceding
paragraph and shown in fig. 2.
The formula and tables are, therefore, strictly applicable only
to wet and dry bulb temperatures as determined by means of the
sling, or whirled psychrometer, or some equivalent form of appa-
ratus, in which the wet bulb especially is subjected to a strong
current of air, the velocity of which is not less than 15 feet per
second.
MAXIMUM PRESSURE OF AQUEOUS VAPOR. — The amount of
saturated aqueous vapor that can exist in any given space depends
entirely upon the temperature. It appears that the vapor may be

10
supersaturated under certain peculiar conditions, but this is a
special and an unstable state of nature which need not be consid-
ered in the present connection. When the vapor is saturated, it
will exert a certain pressure which varies with the temperature
and which so-called "maximum pressure " has been measured with
greater or less precision over a long range of temperature from
about 60° below zero F. to far above the boiling point of water.
The hygrometric tables used by the Weather Bureau since 1886
have been based on the formula given above but used in a slightly
modified form. The vapor pressures employed were derived from
Broch's reduction of Regnault's observations.* All the values
given by these tables at temperatures below the freezing point are
noticeably higher than Regnault's observations. In view of this
systematic discordance, and the further circumstance that Reg-
nault's experiments did not include observations at the extremely
low temperatures frequently recorded at Weather Bureau stations,
the writer, in 1891, made a new determination of the maximum
pressure of aqueous vapor at low temperatures.!
In the course of these experiments it was found an easy matter
to reduce the temperature of the water employed many degrees
below 32° F., without freezing it, and in these cases the vapor
pressure was higher than the pressure from ice at the same temper-
ature. Independent experiments in Sweden, by Julius Juhlin,
at about this time, led to the same results.
A comparison of the vapor pressures derived from the several
sources mentioned, show that Broch's computed values at low tem-
peratures do not agree at all well with Regnault's experiments,
from which they are derived, whereas the experimental results of
Regnault, Juhlin, and the writer agree very closely.
At temperatures below 32° F., therefore, it has been considered
necessary to reject Broch's values, and the vapor pressures over
ice, as deduced from the writer's experiments, have been used in
the calculation of the following tables. These values are given
in the several columns headed "Vapor pressure, e." At tempera-
tures above 32° F., the values taken from Broch's tables are em-
ployed, and likewise recorded in the appropriate columns headed
"Vapor pressure, e." At 32° F., the value for the vapor pressure
found by the writer from the mean of a large number of experi-
ments, was identical with that of Broch ; hence there is no break
in the continuity of the two tables at the point of junction.
The atmospheric pressure at the great majority of Weather Bu-
reau stations ranges from 28 to 31 inches, and to obviate the neces-
sity of any correction for pressure or interpolations two tables

for pressures of 29 inches and 30 inches, respectively, have been
computed. Considerable portions of these two tables are simply-
duplicate impressions from the same electrotypes, but this duplica-
tion not only secures accuracy but greatly facilitates reduction of
observation at numerous stations. Three additional tables at 27,
25, and 23 inches, respectively, have been added for the reduction
of observations at correspondingly elevated stations.
VAPOR PRESSURES AT HIGH TEMPERATURES. — Table XI is
added at the end of the series in response to numerous requests
for tables giving relative humidities at high temperatures, and
gives the vapor pressure, in inches of mercury, for each degree of
temperature from 100° to 445° F. The values in this table, up to
and including 212°, have been taken from Broch's tables. Above
212° the values are reproduced in English units from Regnault's
original tables.* Broch's values have all been reduced to standard
temperature and nianometric units at sea level and latitude 45°;
Regnault's values are for the latitude and elevation of his labora-
tory in Paris, viz, 48° 50' 14" north latitude, and 60 meters (197
feet) above the level of the sea. There is thus a slight discord-
ance between the different parts of the table, but the effect is
very small.
The psychrometric formula given above can not be used for tem-
peratures higher than 130° to 140° F., for the reason that the con-
stants of the equation have been deduced from experiments only
at ordinary temperatures, and the use of the formula for the
reductions of observations at high temperatures would give only
coarsely approximate results.
Probably the most available method of determining humidities
at high temperatures is by use of the dew-point apparatus described
on page 7, which is susceptible of a great variety of forms, and
gives directly the temperature of the dew-point. Table XI then
gives the corresponding vapor pressure. The relative humidity
is obtained by dividing this pressure by the pressure given in Table
XI corresponding to the air temperature. For example, suppose
it is found the temperature of the dew-point of the air in a drying
oven is 115°, and that the temperature of the air is 205°. From
Table XI the vapor pressure at 115° is 2.975 inches, and at 205° is
25.99 inches, hence the relative humidity is 2.975 -4- 25.99 = 11 per
cent.
THE WEIGHT OF AQUEOUS VAPOR (ABSOLUTE HUMIDITY).—
The weight of a cubic foot of aqueous vapor at different temper-
atures and percentages of saturation is sometimes called the abso-
lute humidity.
* Memoires de L'Academie des Sciences de L'lnstitute de France, Tome XXI,
1847.
12
Saturated aqueous vapor is but little more than half as heavy as
the same volume of dry air under like conditions of temperature
and pressure. In all ordinary computations it is assumed that the
expansion and contraction of partially saturated aqueous vapor is
in accordance with the same laws as apply to air and ordinary
gases, which do not easily condense to the liquid state.
The adopted density of saturated aqueous vapor is not deter-
mined directly from experiment, but is deduced theoretically from
the observed fact that two volumes of hydrogen and one of oxy-
gen, combine to produce two volumes of water vapor.
The weights of unit volumes of hydrogen, oxygen, and dry air
are accurately known, from which the specific gravity of aqueous
vapor is found to be 0.6221.
If English units of temperature, pressure, and weight are used,
we find the weight of a cubic foot of saturated aqueous vapor in
grains is :
F'
L1-7449~l + 0.002037 (*- 32)'
This formula gives the weights found in the column headed
" 100 " in Table XII.
USE OF TABLES EXPLAINED.
In reducing psychrometic observations, regard should be had to
the atmospheric pressure at the time, and results deduced from
the tables based on a pressure nearest that observed. Interpola-
tion for intermediate pressures need not be made, arid when the
pressure is not observed, an approximate value, known to be
appropriate to the particular elevation of the point of observation,
may be employed.
The psychrometric observations made at Weather Bureau sta-
tions will be reduced by means of the tables based on an air pres-
sure which is numerically nearest the average or normal station
pressure, and detached copies of appropriate tables for the several
stations will be furnished for the convenience of observers in their
daily work.
The temperatures t and t' of the wet and dry bulb thermometers
will be read, and the difference t — t' computed to the nearest tenth
of a degree. It is desired that the dew-point especially be taken
out to the nearest whole degree, and the tables have been expanded
with a view to obviating difficult interpolations. In some cases,
however, double interpolations must be considered, but the proper
result can often be obtained by simple inspection. When the air
is very dry, however, a careful calculation is necessary.
13
An examination of the dew-point tables especially will show
that diagonal lines exist, inclining downward and to the right,
along which the tabulated values of the dew-points are constant
or change very little. As a result of this circumstance, when the
observed values of air temperature and t — t' fall even roughly
midway between the values given in the arguments of the table,
double interpolation will, in general, not be required, as the cor-
rect result will be obtained by dropping both intermediate frac-
tions, even where they exceed half the interval — that is, take out
the dew-point corresponding to the arguments next lower than the
air temperature and t — t' observed.
When one of the observed quantities is quite near a tabulated
value, the latter will be used, and the interpolation, if any is
required, based on the other quantity only.
When the air is very dry the successive values in the table differ
so much that carefully calculated interpolations will often be
required.
The following examples of the use of the tables illustrate how
the foregoing principles are applied :
EXAMPLE No. 1.— AIR PRESSURE, 29.7 INCHES.
Air temperature, £=75.0°.
Depression of the wet bulb, (£-0 = 9.5°.
In this case the table for 30 inches air pressure should be used,
and we find on page 18, opposite 75° in column 9.5° :
Dew point= 60°.
On this same page, opposite 60° under the column e, we find :
Vapor pressure, e=0.$17.
Finally, on page 58, opposit 75° in column 9.5°, we find:
Relative humidity =60 per cent.
EXAMPLE No. 2.— AIR PRESSURE, 25.8 INCHES.
Air temperature, £=67.8°.
Depression of the wet bulb, (t—f) = 3. 2°.
In this case the table for 25 inches on page 43 must be used, and
the tabulated values which must be considered are :
3.0°.
3.5'.
67° _

14
A double interpolation seems to be required in a case of this kind,
but it will be observed that if we drop both the intermediate frac-
tions and take the dew-point corresponding to air temperature, 67°,
and £—£'=3°, we get dew-point 63°, which is the correct result to
the nearest degree. We thus have for the complete reduction of
this observation :
Dew-point=63°.
Vapor pressure =0.575.
Relative humidity— 85 per cent.
EXAMPLE No. 3.
The following example of the use of Table XII indicates how
interpolation for intermediate percentages of saturation may be
effected :
What is the weight of vapor in a cubic foot corresponding to a
temperature of 70° and a relative humidity of 83 per cent?
At 70° and 80 per cent the weight is.. 6.384 grains.
The additional weight for 3 per cent is TV the weight
for 30 per cent, viz _. .2394 grains.
Hence, the weight at 70° and 83 per cent is. . _ 6. 623 grains.

APPENDIX TO PSYCHROMETRIC TABLES.
(JANUARY — , 1910. )
The following remarks and suggestions are presented at this
time, for consideration in connection with the instructions given
on pages 5 to 14, both inclusive :
1. Preparation of tvet-bulb thermometer. — Certain precautions
must be observed in preparing and fitting muslin covering of the
wet bulb, as follows :
(a) Fine, preferably loosely woven, muslin is the best, and, if
new material is used, it must first be thoroughly washed with
water to remove all sizing as far as possible.
(6) The covering must be carried up on the stem of the ther-
mometer above the bulb a distance so that the stem near the bulb,
as well as the bulb itself, is cooled by the evaporation.
(c) The muslin must be thoroughly wetted when a new piece is
to be applied to the bulb, and fitted in the manner explained on
page 5.
2. Use of psychrometer at low temperatures. — When the tem-
perature is far below the freezing point, for example, in the
vicinity of 0° F., or lower, the psychrometer is really not a very
reliable instrument with which to measure humidity ; in fact, the
quantity of moisture in the air at such times is so small that only
the most refined measurements suffice to determine the actual
quantity with accuracy. The best that can be done with the psy-
chrometer is to determine the temperature of evaporation with
all the accuracy possible. For this purpose the muslin should be
wetted in cold water and some of the excess of water shaken off
the bulb which is then allowed to cool and the water to freeze.
The ice-covered bulb is then whirled in the customary manner,
but a very considerable time may be required in order to get the
absolute minimum evaporation temperature. The whirling of the
sling psychrometer or of the whirling apparatus at an excessive
speed under these conditions is both dangerous and unnecessary.
The quantity of ice being evaporated is, at the best, small, and
the rate of cooling is necessarily slow, so that it is simply a ques-
tion of time, and moderate time must be allowed for the instru-
ment to reach the minimum temperature. Even under most
favorable conditions, the difference between the wet and the dry
bulb readings is very small, and careful regard must be paid to the
(85)
86
small corrections for instrumental errors which all thermometers
almost always require to be applied in order to give correct
temperatures.
3. Determination of atmospheric moisture at high temper-
f _ atures. — T h e accompanying
psychrometric tables are com-
puted to an air temperature
of 140° F., but it is recog-
nized that the moisture con-
tents of the air at much higher
temperatures than this are of-
ten desired in important com-
mercial operations. Unfortu-
nately the necessary check ob-
servations for determining the
moisture contents of the air
from readings of the wet and
dry bulb thermometers have
never been carried out, and it
is unwise to extend the present
tables to include these tempera-
tures, as the result would prob-
ably prove to be highly inac-
curate. Where observations
on humidity at these high tem-
peratures are necessary, prob-
ably some other form of ap-
paratus will have to be used.
For example, definite volumes
of air should be drawn off from
the hot space through a suit-
able gas meter, or equivalent,
and the quantity of moisture
contained therein absorbed by
chemical reagents and measured
by determining the increase in
weight of the absorbent. It is
impracticable, within the scope
of this pamphlet, to give details
of this method of determining atmospheric moisture.
4. Special use of tables in factories, etc. — In factories, drying
rooms, and other localities where conditions prevent the use of
the simple sling psychrometer, some form of whirling apparatus,
such as shown in figure 3, may be employed. If this is not practi-
cable, and if stationary wet and dry thermometers can be used,
FIG. 3. — WHIRLING APPARATUS.
87
they should be placed in the proximity of a ventilating fan, OP
other device, that will give the necessary ventilation of the wet
bulb. The tables herein will not give accurate results if readings
of stationary wet and dry thermometers in stagnant air are
employed.
5. The whirling apparatus shown in figure 3 is used at all
regular telegraphic-reporting stations of the Weather Bureau.
It is permanently mounted within a wooden shelter having
louvered sides and double top, installed on suitable steel or wooden
supports with the bottom about 10 feet above roof or ground.
The crank shaft projects through the front of the shelter, and
when observations are being made the apparatus is operated from
the outside by means of the crank handle. The wet and dry ther-
mometers are thus completely protected from strong radiation,
rain, etc. , and are perfectly ventilated by being rapidly revolved.
